IBLASTING PAPER.

' Application filed JulylO,

This invention relates to blasting paper for mlning and other purposes and its PI'lmary object is to provide paper for form-- ing containers of. cylindrical or like shape of various lengths and diameters to produce tubes, cartridges or shells of'various size and thicknesses so as to accommodate them selves for holes bored for blasting purposes.

A further object of the invention is to provide ablasting paper arranged in roll formation whereby any quantity can be torn or cut from the roll and shaped in tubular formation to provide a container'for holding blasting powder and the like to pro :duce blasting tubes, cartridges or shells havmg walls of a number of thicknesses sealed from end to end and in a. manner to blasting powder and the like, and the adhesive substanceis so arranged on said roll of paper that it is impossible to roll a sheet in tubular form without having the adhesive substance disposed in a correct position to provide a positive and permanent seal or seam for the tube.

A still further object of the invention is to provide water proof blasting paper hav-' ing' adhesive substance thereon, whereby tubes and the like can be formed from said paper and filled with blasting powder and the like and sealed to the exclusion of water and other similar damaging agents or elements.

Thisinvention also consists in. certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim. j I

In describing my invention in detail, reference will be had to the accompanying.

drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a perspective view of a roll of 1926. Serial No. 121,681.

the blasting paper which forms-the subject 'matter or" thepresent invention.

Figure 2 is'an elevation of a tube formed from a sheet of shown in Figure r Figure 3 is a view showing the applic'm tion of a completed tube formed. bymy novel method'and being applied in a shot hole.

paper taken from'the roll Figure 4 isa perspective viewofa roll of paper showing a modified form ofsealing means. I

Figure 5 is a similar view of a tube secured by the modified form.

Referring to the drawings in detail and more particularly to Figure 1 it will be noted that the blasting paper is to be arranged in rolls 1 and has its longitudinal edges coated with adhesive substance 2 and.

on both the upper and lower surfaces of said longitudinal edges, if desired.

Sheets of various lengths are adapted to be torn or vcut from the roll, the length of the sheet depending-of course upon thesize of a tube which is to be formed from said sheet, then the sheets are rolled uponthem- ,selves in tubular formation as at 3 as shown in Figure 2.

lt is obvious that the tube can be rolled to a size to fit the shot hole. asvar iousjsize holes are made when it is necessary to use different size drill bits or the like.

Of course the tube as shown in Figure 2 when completed can be inserted in the shot hole in the manner asshown in Figure 3 and a quantity of dry clay dust can be putin said tube and will gravitate to form a seal across the bottom of said tube as shown at 4, the powder charge may then be introduced as shown at 5 anda seal of powder 6 to cover the powder, with the fuse 7 applied through the clay dust and into the powder charge.

However, the complete shell or cartridge can be formed before the tube'is placed in a shot hole, or a" complete powder charge maybe put in the tube and the ends crimped and sealedover said charge after-a fuse 7 has been inserted in the powder.

A modified form, of sealing means is disclosed in Figure 4c Which'shows a roll provided with adhesive tape Shaving a portion thereof secured to the longitudinal edge of the paper of the roll. while the remaining portion of the tape extends beyond the edge for securing the paper torn'from the roll, in tubular form having a number of thick nesses as shown in Figure 5 0f the drawings.

The paper'ma-y be properly Water proofed so asto retain the charge in a dry *state atall times. 7

The paper of the rolls as shown in,

ures 1 and 4, are to have printed or ether-v wise formed thereon at intervals in its length advert-rslng matter, and of course the paper.

could-be divided in block formation to act as afg'uide in cutting or tearing the paper from the roll, as :will be obvious. v i From the above description and the draw ings, it; Will be apparent that any size "or @length sheet rna roll 1 and the is 'eet-rolled to a number of be torn or cut -ffrom the thicknesses in tubular formation and retained in said; formation. by the gutnme'd 01 adhesive strip 2' or tape 8 which seals the tubeifrom end to end to provide a water proofxcontainer forpowder to? be used for blasting or other purposes; Z

in the scope-of'theappended claim;

What I claim is: r a In a blasting charge con'tainl'er, aYIOHOfblasting paperhaving adhesive material on its longitudinal edges, said roll being adaptr ed so that a sheet'of paper can bei ta'ken therefrom ,with adhesive material on two edges thereof for forming a tube by rolling V the sheet 'fr'ornueither ofitssaidwtWO-Iedges whereby one ofthe' .edges' may-be usedforsealing. the sheet in tube formation,

In testimonywhereof I' afiix my signature.
